multiple Transfer-Encodings?

Hi all, are there real-world examples of people using multiple
Transfer-Encodings in the same request? rfc2616 seems to allow
it as long as chunked is also used, but we don't have support
for anything other than chunked.
Heck, the only example I can think of for chunked requests in the
request is "curl -T-" to make PUT requests from stdin (I use that
every single day, but I don't think the rest of the world does).
